ROBERT BRUCE AND SIDNEY THOMAS BRUCE, OF MAR-SHALL, MISSOURI.

SPECIFICATION forming part of Letters Patent No. 305,285, dated September 16,1884.

Application filed May 17, 1884. (No model.)

To all whom it may concern:

Be it known that we, ROBERT BRUCE and SIDNEY T. BRUCE, citizens of the United States, residing at Marshall, in the county of Saline and State of Missouri, have invented certain new and useful Improvements in Plows and we do declare the following to be a-full, clear, and exact description of the invention, such as will enable others skilled. in the art to which it appertains to makeand use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is aside view, part sectional, of our device. Fig. 2 is a plan view of the same. Fig. 3 is a transverse section, and Fig. 4. is a detail view.

This invention has relation to wheel-plows; and it consists in the construction and novel arrangement of devices, as hereinafter set forth,

In the accompanying drawings, the letter A designates the beam of the plow, which is pivoted near its front end between the arms 13 and C of a holder, D, which consists, essentially, of said arms and a transverse vertical plate, E.

F represents the axle-ban, having vertical socketbearings a at its ends, to receive the pintles b of the journal-pedestals .G of the wheels, said pedestals having brace-arms c, which extend forward and upward, and are pivoted to the ends of a front guide-bar, H, which extends transversely, being located a short distance in front of the axle-bar F. Pivoted links K connect the ends of the axle-bar to the ends of the guide-bar, which is made a little longer than the axle-bar, to facilitate turning in short compass. The transverse holder-plate E is pivoted at one end to the axlebar, as shown at d, and at its other end said plate is provided with a vertical curved slot, 6, adapted to engage a clamp-screw, f, which is secured to the axle-bar or to a bearing-plate or wear-plate, g, secured thereto. A similar wear-plate is arranged to serveas a bearing for the pivoted end of the holder-plate E. From a central lug, h, of the plate E ex tends forward, through a bearing, k, the draftrod I. The arm Bis rearwardly extend ed from the holder-plate E, and provided at its end with a segment-gear, Z, to engage a segmentgear, 121, on the forward end of alever-standard, L, which is curved, extending downward in rear of the plow-beam, and carrying a gagewlieel, M. This wheel, operating in connection with theholder-plate and the front wheels, gages the depth of the plow in the ground.

I11 order to fasten the plow-bean1 when the plow is adjusted for depth, as well as to enable the driver, seated on a seat, S, which is secured to an arm of the holder, to readily make the adjustment, the devices hereinbelow described are employed. The forward end of the plowbeam, in front of its pivot 12, is toothed or provi ded with a toothed segment, as indicated at s, which engages a segment gear, 2, which is pivoted between the front portions ofthe arms B and G of the holder, said portions being made broad and being circularly curved at their upper edges, as shown at r. These edges are toothed to engage a pinion or pinions on the lever '1, which is rigidly joined to the segment-gear z. This lever is provided with a slide-lock, t, which is operated by means of an auxiliary handle, a, which is pivoted to the main lever near its own handle a. By manipulating the handles the slide-lock may be engaged or released. \Vhen released, the leverT can be operated by the driver to turn its segment 2, thereby raising or lowering the plow-beam. The driver can therefore easily adjust the depth of the plow, or raise it out of the ground whenever it may be advisable. The lateral pitch of the plow-such as may be required, for instance, in hillside-plowingis determined by adjusting the transverse holder-plate E, to which the beam is connected, the adjustment being secured by means of the clamp-screw.

Having described this invention, what we claim, and desire to secure by Letters Patent, 1s

1. The combination, with the transverse anend and pivoted to said holdenplate, the segment-lever, and the gagewheel lover or stan djournals, of the adjustable holder-plate 0011- nected to the axle-bar, the plow-beam pivoted to arms of the holder-plate, and the adjustinggear of the main lever and of the lever-standard of the gage-wheel, substantially as specified.

4. The combination of the front wheels and axle, the holder-plateB E, the rear wheel, and the arm L, the pivoted plow-beam, the lever adapted to raise the front and rear ends of the plow-beain by one operation of the said lever, and lower it by a reverse movement of the same lever, substantially as specified.

5. The combination, with the axlebar, of the transverse bar H, of greater length than the said axle-bar, the wheel-pintles hinged to the said axle-bar, the pedestals having branch arms 0, and the connectingarms K K,whereby the plow may be turned in a narrow space, substantially as specified.

In testimony whereof we affix our signatures in presence of two witnesses.

ROBERT BRUCE.

SIDNEY THOMAS BRUCE.
